Auto record a single user's whole screen without popup widows

We need to auto record the whole screen of a user without any additional popups. Someone will attempt an online exam, and as he clicks on the start button, we need to auto record the whole user screen until the exam is over or the user clicks on the end-recording button. Is it possible to record a single user’s screen with Jibri?

Till now, we have been able to record the meetings using the jibri. But due to changed requirements now, we need to auto record a single user’s screen. if possible, to avoid of a popups etc as well.
